Looks like a purple haze.

DITTO!

Not to get too technical, but I believe it's not a Purple Haze, but the variant called a Purple Craze. The only difference between the two is that the "Haze" uses floss (originally) or dry fly dubbing (later), and the "Craze" uses flash dubbing, usually purple Ice Dub or something similar to give it the extra shimmer in the water, as in the first two pictures.

The Purple Haze is an awesome fly for the SNP. Another great attractor pattern foe brokkies in the SNP or in the Smokies is Dorsey's Limeaide in #12 or #14.

BigY does have the "Sparkle" variety, I ordered the regular Purple Haze. Today there was active hatch going on with little yellow bugs (I assume mayflies - correction Stonefly) , I was going to change flies to a yellow drake or light cahill but the Purple Haze was so hot I didn't bother.

Yup, that is big void with me, I am not good at matching hatch. I do pay more attention and look up insects once I get home. For me it's easier with nymphs than flying stage.

That’s even simple enough for me to remember.....thanks.

While there is a lot to be said for good fly ID, I wouldn't leave a fly that was working well either.

I received some Purple Hazes from both Ascent Fly Fishing and Big Y Fly company. From each company I bought about 15 - 20 different flies. Below is quick review:

Big Y sent flies all clumped into a single small plastic cup with cap, which made it cumbersome to separate and see what they were. Ascent sent with each fly lined up by type and size stuck to thin styrofoam (pic below).

Below is bad pic for comparison purposes, but the Ascent purple is much shinier with sparkles of some sort and also body is thicker than Big Y's, the Big Y's purple is "matte" like, like a muted purple. I could see Ascent's being a much better attractor.

Ascents parachute is tighter and more refined looking, Big Y's is looks looser and unkept. Ascents tail is little longer and strands have nice separation and flair at end. Big Y's is tighter without natural flair towards end.

Cost - Big difference here, Ascents is 2x cost of Big Y. Big Y is .67 cents down to .63 for quantity, and Ascent is $1.25 and down to $1.00 for 12 or more.

Next time on water I will test both to see if Ascent is worth almost 2x more than Big Y. But overall Ascent's is much better looking fly.

I like to use Murray's Little Yellow Stonefly dry or some approximation thereof as my fly tying skills aren't always pretty. Some of these stoneflies are lime green colored but otherwise look identical to me. Whatever color is present the trout seem to take the yellow colored artificials just as well. To my experience this is one of the more common and reliable hatches I've found in Virginia mountain streams.
